Description

Technical Field

[0001] The invention relates to the field of ship processing, in particular to a detection device for ship hull construction. Background Art

[0002] Ship grinding is the work of removing rust, scars and splashes during the shipbuilding process. The characteristics of grinding work are to remove rust, scars and splashes according to the process requirements of shipbuilding, so that the ship meets the requirements of classification societies and shipowners, and prepares for the painting of the ship. Free edge grinding is an indispensable and very important process in the hull construction process. The angle of the same edge during the hull grinding process needs to be kept consistent, and because the length of the ship's edges is relatively long, it is easy for the curvature of the edges to be inconsistent.

[0003] However, currently, the curvature detection of the free edge of the hull after grinding is mostly carried out using an R gauge. The R gauge has low measurement accuracy after contacting the contact surface during detection, and the detection efficiency is also low. Summary of the invention

[0004] In view of the existing problems, the present invention provides a detection device for ship hull construction, which can effectively solve the problems raised in the background technology when used in combination.

[0005] To solve the above problems, the present invention adopts the following technical solutions:

[0006] A detection device for hull construction includes a first detection member and a second detection member, wherein the first detection member and the second detection member are both L-shaped components with equal side distances, and the first detection member and the second detection member are both provided with measuring arc plates on their inner sides, an adjustment slot is provided on one side of the first detection member, a laser head slot is provided on the adjustment slot near the edge of the measuring arc plate, a sliding block is provided on the outer side of the adjustment slot, a laser pen holder is provided on the outer side of the laser head slot, an arc slot is provided below the laser pen holder, a laser penetration tube is installed on the lower surface of the arc slot, a laser receiver is installed on the side of the second detection member located near the first detection member, and an indicator light is provided above the second detection member.

[0007] As a further solution of the present invention: a storage bin is opened on the inner side of the first detection member, magnet bins are opened on the inner side walls of the first detection member on both sides of the storage bin, an adsorption magnet is installed inside the magnet bin, a roller frame is installed inside the storage bin, and a compression spring is connected between the roller frame and the storage bin.

[0008] As a further solution of the present invention: a control module electrically connected to the indicator light is installed on one side of the laser receiver and located inside the second detection component, and a power supply module is arranged inside the second detection component.

[0009] As a further solution of the present invention: a limit block is installed inside the adjusting slide groove at one end of the sliding block, and a connecting rod is connected between the laser pen holder and the sliding block.

[0010] As a further solution of the present invention: a pointer is provided on the upper surface of the first detection member, and a marking groove is installed on one side of the indicator light inside the second detection member.

[0011] As a further solution of the present invention: the laser head slide groove and the adjustment slide groove have the same curvature as the laser receiver.

[0012] As a further solution of the present invention: the roller frame is rotatably connected to the storage bin, and a roller is installed at the free end of the roller frame.

[0013] As a further solution of the present invention: the second detection component, the indicator light and the control module are all electrically connected to the power supply module.

[0014] As a further solution of the present invention: the sliding block is slidably connected to the adjusting sliding groove through the limiting block.

[0015] As a further solution of the present invention: an angle plate is provided on the side surface of the first detecting member outside the adjusting slot.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The center of the circle formed by the laser head slide and the adjustment slide coincides with the center of the circle formed by the measuring arc plate. Therefore, when the adjustment slide block drives the laser pen holder to move as a whole, the motion trajectory of the light emitted by the laser tube under the laser pen holder is just below the measuring arc plate. Therefore, when the size of the detected edge is qualified, the corresponding laser receiver cannot receive the light signal, which can facilitate the judgment of whether the size of the detected edge is qualified, and the detection accuracy is also relatively large.

[0018] 2. Use the roller installed at the free end of the storage bin to roll on the hull to avoid directly controlling the first detection piece to slide, which may cause friction damage to the surface of the measuring arc plate or the surface of the hull, and facilitate the control of the movement and adjustment of the detection piece on the hull.

[0019] 3. By setting the light receiver to a component with the same shape as the measuring arc plate, and the arc of the light emitted by the laser tube penetration is also consistent with the arc of the measuring arc plate, during the movement of the laser tube penetration, any unqualified size at any position of the edge to be measured can be detected to ensure accurate measurement.

[0020] 4. Use the marking groove to leave a mark on the hull. After the inspection from the mark position to the position of the first inspection piece is completed, the second inspection piece is arranged to the uninspected position, and then the first inspection piece is placed at the marking position through the pointer to ensure that all positions of the entire polished edge can be inspected.

DETAILED DESCRIPTION

[0029] The present invention is further described below in conjunction with specific inventions, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present invention.

[0030] In the description of this specification, the description with reference to the terms "this embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in combination with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example, and the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0031] like Figure 1 , 2 As shown in Figures 4 and 5, the present embodiment provides a detection device for hull construction, including a first detection member 1 and a second detection member 2, both of which are L-shaped components with equal side distances, and a measuring arc plate 11 is provided on the inner side of the first detection member 1 and the second detection member 2, the curvature of the measuring arc plate 11 is consistent with the curvature of the circular arc to be polished as required, and when detecting different polished edges, the first detection member 1 and the second detection member 2 with different measuring arc plates 11 are replaced to achieve the detection, an adjustment slot 5 is provided on one side of the first detection member 1, and a laser head slot 3 is provided at the position of the adjustment slot 5 near the edge line of the measuring arc plate 11, in the side view angle of the first detection member 1, the center of the circle formed by the laser head slot 3 and the adjustment slot 5 coincides with the center of the circle formed by the measuring arc plate 11, and a sliding block 6 is provided on the outer side of the adjusting slot 5, and the end of the sliding block 6 is arranged inside the adjusting slot 5. A limit block 601 is provided, and the sliding block 6 can slide inside the adjusting slot 5 through the limit block 601. The outer side of the adjusting slot 5 is provided with an angle disk 10 on the side surface of the first detection member 1. The angle disk 10 can be used to observe the adjustment angle of the sliding block 6. The arc path of the sliding block 6 coincides with the central arc of the adjusting slot 5. A laser pen holder 4 is provided on the outer side of the laser head slot 3. An arc groove 401 is provided below the laser pen holder 4. A laser penetration tube 402 is installed on the lower surface of the arc groove 401. A connecting rod 602 is fixedly connected between the laser pen holder 4 and the sliding block 6. The laser pen holder 4 is located inside the laser head slot 3 and a limit member is also installed. In the process that the laser penetration tube 402 is driven to move by the laser pen holder 4, the arc path of the moving light generated by the laser penetration tube 402 is just on the lower surface of the measuring arc plate 11 and will not be blocked by the measuring arc plate 11.

[0032] like Figure 2-4 As shown, a storage bin 9 is provided on the inner side of the first detection member 1, and magnet bins 801 are provided on both sides of the storage bin 9 on the inner side walls of the first detection member 1, and an adsorption magnet 8 is installed inside the magnet bin 801, and a roller frame 901 is installed inside the storage bin 9, and a compression spring 902 is connected between the roller frame 901 and the storage bin 9. When performing detection, a downward pressure is applied to the storage bin 9, and the compression spring 902 is compressed under the action of pressure, so that the roller frame 901 is stored in the storage bin 9 as a whole, and the first detection member 1 as a whole will be adsorbed on the outside of the hull through the action of the adsorption magnet 8. At the same time, when controlling the first detection member 1 to detect different positions, the roller installed at the free end of the storage bin 9 can be used to roll on the hull to avoid directly controlling the first detection member 1 to slide, which will cause friction damage to the surface of the measuring arc plate 11 or the surface of the hull.

[0033] like Figure 1 , 3 As shown in Figures 4, 6 and 7, the second detection member 2 is located on a side close to the first detection member 1 and is provided with a laser receiver 7. The laser receiver 7 is a component with the same shape of arc as the measuring arc plate 11. An indicator light 202 is arranged above the second detection member 2. One side of the laser receiver 7 is located inside the second detection member 2 and a control module 203 electrically connected to the indicator light 202 is installed. All control units for the laser receiver 7 and the indicator light 202 are integrated inside the control module 203, and the mutual transmission and conversion of electrical signals can be realized. A power supply module 204 is arranged inside the second detection member 2. The second detection member 2, the indicator light 202 and the control module 203 are all electrically connected to the power supply module 204, because the path of the moving arc of the light generated by the laser penetrating tube 402 is just in the measuring arc. The lower surface of the measuring arc plate 11 is not blocked by the measuring arc plate 11. When the first detection member 1 is fitted as a whole to the outside of the edge to be measured, if there is no error in the curvature of the position to be measured, the light generated by the laser tube 402 cannot be transmitted to the position of the laser receiver 7. By controlling the sliding block 6 to slide as a whole inside the adjusting slot 5, the light will move at the connection between the measuring arc plate 11 and the position to be measured. When there is a size that does not meet the requirements, there will be a gap at the connection between the measuring arc plate 11 and the position to be measured. The light generated by the laser tube 402 is irradiated to the outside of the laser receiver 7 through the gap. After the laser receiver 7 receives the light, the signal generated is transmitted to the control module 203, and the indicator light 202 is processed to work to prompt the user of the bad position.

[0034] like Figure 1 , 3As shown, a pointer 12 is provided on the upper surface of the first detection member 1, and a marking groove 201 is installed inside the second detection member 2 on one side of the indicator light 202. After the second detection member 2 is arranged at the position of the first inspection, a marking pen is used to pass through the marking groove 201 and leave a mark on the hull. After the inspection from the marked position to the position of the first detection member 1 is completed, the second detection member 2 is arranged to the uninspected position, and then the first detection member 1 is placed at the marking position through the pointer 12, to ensure that all positions of the entire polished edge can be inspected.

[0035] The working principle of the present invention is as follows: when in use, first determine the first detection member 1 and the second detection member 2 to be used according to the R angle size of the edge to be detected, first arrange the first detection member 1 at one end of the detection edge, and when performing detection, apply downward pressure to the first detection member 1, so that the compression spring 902 is compressed under the pressure, and the roller frame 901 is stored in the storage bin 9 as a whole, and the first detection member 1 as a whole is adsorbed on the outside of the hull by the adsorption magnet 8, and the side of the second detection member 2 with the laser receiver 7 is correspondingly arranged on the outside of the detection edge, and a marker is used to pass through the marking groove 201 to leave a mark on the hull, and the laser tube piercing 402 on the outside of the first detection member 1 and the laser receiver 7 on the outside of the second detection member 2 are opened, and a force is applied to the sliding block 6 to control the sliding block 6 to slide in the adjusting groove 5, and at the same time, the laser pen holder 4 is driven to move under the action of the connecting rod 602, and in the process of the laser tube piercing 402 being driven to move by the laser pen holder 4, the laser tube piercing 402 The path of the moving arc of the generated light is just on the lower surface of the measuring arc plate 11 and will not be blocked by the measuring arc plate 11. If there is no error in the curvature of the position to be measured, the light generated by the laser tube penetration 402 cannot be transmitted to the position of the laser receiver 7. By controlling the sliding block 6 to slide as a whole inside the adjusting slide groove 5, the light will move at the connection between the measuring arc plate 11 and the position to be measured. When there is a size that does not meet the requirements, there is a gap at the connection between the measuring arc plate 11 and the position to be measured. The light generated by the laser tube penetration 402 is irradiated to the outside of the laser receiver 7 through the gap. After the laser receiver 7 receives the light, the signal generated is transmitted to the control module 203, and after processing, the indicator light 202 will work to prompt the user of the bad position. After the detection from the mark position to the position of the first detection member 1 is completed, the second detection member 2 is arranged to the undetected position, and then the first detection member 1 is placed at the marking position through the pointer 12 to ensure that all positions of the entire polished edge can be detected.
